Hello All, I connect to the Internet with a Telstra 4GX mobile modem, and the Netgear cradle for it. I want to put at least one network printer on a home network, but not expose it to the Internet. I would appreciate any recommendations about a router and or firewall. I currently have two PC's on ethernet cables plugged into the cradle, and choose to not use the wi-fi. I would like to try for something that can be run from a 12 volt battery, I can run the modem and cradle that way, although not yet set up that way. In that light I am also considering getting a Raspberry Pi 4+ as a desktop, and using a 12v 24" television as the monitor. I am considering going the 12v route because I do get power flicks now and then, and also am considering going off grid. A native 12v DC system will waste less power than using an inverter to go 240V AC and then back to the DC, along with being a separate system that has the potential to be left running 24x7, while I do switch the various items off at the moment. I had considered a Raspberry Pi for a firewall, but I would prefer to run something with two full Ethernet ports. I know I could add one to a Raspberry Pi with a USB to Ethernet dongle, but there are bandwidth considerations within the Raspberry Pi. That may not matter as the broadband mobile is not always particularly quick, or the Telstra network and tower may be the limiting factor, but still thinking. I am also giving consideration to my limited budget, but trying to take a step at a time that will not be the wrong way. I am prepared to save up for better devices that will last me better, but that may take longer to implement. Regards, Mark Trickett
